Industrieviertel (English: Industrial Quarter),[p] or Viertel unter dem Wienerwald, is the southeastern quarter of the four quarters of Lower Austria (the northeast state of the 9 states in Austria). It is bordered on the north by Vienna and the Weinviertel, to the west by the Mostviertel, and to the south and east by the states of Styria and Burgenland respectively. The Vienna Woods (Wienerwald) forms the natural border to the west, and hence the alternate name as "Quarter below the Wienerwald".
The Industieviertel is made up of the following districts:
Geographically, the Industrieviertel is characterized by the level of the stone field, with its brown earth soils on tertiary molasse, just as the Vienna Basin rests on Tschernosem soils. The landscape in the area of the Vienna Basin is composed of vast agricultural areas, industrial areas and vineyards along the Thermenlinie ("thermal line") geological fault line of thermal springs. In the stone field, on brown earth soils, are vast pine forests which had been created under Empress Maria Theresa, to prevent the desertification of the arid landscape. On the slopes of the Wienerwald, different forest types have grown, depending on the climatic conditions. In the east, the view extends to the horizon, the so-called "gates" that Wienerneustadt gate, which Brucker Hainburger gate and gate to separate the Rosaliengebirge and Leitha Mountains, the Hundsheim and the Little Carpathian Mountains. Simultaneously, with the installation of the pine woods, have been used for rosin production during 1761 - 1765, straight on the road between the towns of Wiener Neustadt and Neunkirchen, the so-called Neunkirchner Avenue, started by Joseph Liesganig with the geodetic surveying of the entire monarchy at that time.
The annual mean temperature range, depending on the location, is from 11 °C (52 °F) to 4 °C (39 °F). For example, for Wiener Neustadt (280 metres or 920 feet), the annual mean temperature is around 10.3 °C (50.5 °F), with approximately 630 millimetres (25 in) of precipitation, and snow cover nearly 40 days, about 95 days of frost and sunshine around 1900 hours, in contrast to Semmering with an annual average of about 5.5 °C (41.9 °F), a rainfall of about 970 millimetres (38 in), a snow cover of about 150 days, plus about 150 frost days and approximately 1500 hours of sunshine.
